Defines a new current message.

DWORD vceSetCurrentMessage ( VCEHD vh,
unsigned message)

vh Handle of an open voice object.

message Message number in vh.

• SUCCESS
• CTAERR_FUNCTION_ACTIVE
  Playing or recording is already active on the CTA context.
• CTAERR_INVALID_HANDLE
  vh is not a valid handle to an open voice object.
• VCEERR_INVALID_MESSAGE
  message is out of range for the specified voice object.

• None.

This function defines the current message for the CTA context implied by vh. It is a special case of vceSetCurrentList where the list consists of one message.

Use this function to select a message prior to using position-oriented functions, which include vceSetPosition, vcePlay, vceRecord, vceErase, vceRead, and vceWrite.

vceSetCurrentMessage will return SUCCESS for any message number that is valid for the file type of vh. Otherwise, the return code will be VCEERR_INVALID_MESSAGE.

To define the current message as all messages in vh, concatenated in numerical order, specify VCE_ALL_MESSAGES as the message number.

You cannot set the current message while play or record is active.

Use vceGetCurrentList to query the current message.
